What is the purpose of genome sequencing?
allows for an understanding of how genes function and to better understand certain diseases
provides a pattern that can be compared for similarities
allows desired traits to be expressed
When an organism is genetically engineered, what occurs?
the genome is identical to their parents'
they are made using half the genomes of two different species
the organism contains genes that were transferred from another organism
they are produced by breeding only the individuals with desired traits.
The process by which humans breed only those organisms with desired traits to produce the next generation; selective breeding.
Gene Therapy
Artificial Selection
Natural Selection
Genetic Engineering

Wild foxes are aggressive and unfriendly toward humans. However, Russian scientists have worked since the 1950s to breed a domesticated version of the silver fox. Each year, the scientists choose the tamest foxes to mate together. Gradually, the foxes are becoming more like dogs. They are much more friendly and playful than wild foxes. What technique is used to increase desirable traits in domesticated animals through breeding?
Natural Selection
Genome Selection
Cloning Selection
Artificial Selection
Which of the following statements is true of all genetically engineered organisms?
They have a genome that is identical to their parents’ genome.
They are made using half the genomes of two different species
They contain genes transferred from another organism.
They are produced by breeding only the individuals with desired traits
Genetic technologies are in the news now almost every day. Scientists, engineers, animal breeders, farmers, doctors, and police use genetic techniques to answer questions, grow food, prevent illness, and solve crimes. Read each sentence in the right column that describes a problem that can be solved with genetic technology. Then draw lines to match each genetic technology in the left column with an example of a problem it can solve in the right column
A child is born with a faulty gene that causes a serious disease.
A racehorse owner wants to make an exact copy of his champion horse.
Scientists transfer a fluorescent gene from a jellyfish into a fish to study chemicals in bodies
Scientist want to breed larger cows for larger quantities of meat.
Which organisms have been selectively bred?
Dogs, cats, and livestock animals.
Fish that glow under a black light.
Bacteria that produce insulin.

Which of the following can be a negative effect of cloning fruits and vegetables?
The ability to produce a large amount quickly
Producing products with the same qualities
Not much variation for the organism to survive diseases
The taste is not the same
Genetic (a) is used to give organisms (b) they could not acquire through (c)
Why did scientists create fish that glow under a black light?
To produce more milk or meat.
To track toxic chemicals in the body.
To treat genetic disorders in humans.
To fight disease in the body.
What is the purpose of genetic engineering?
To produce more milk or meat.

What are some concerns about genetic information and DNA use?
The impact it could have on human health and the environment in the future.
The use of genetically modified organisms (GMOs) in our food supply.
Who can access DNA information and how it will be used.
All of the above.
